Abstract
The unthreading and rethreading of pseudorotaxane 1, which contains two p‐phenylene spacers linking two bipyridinium units and a central 1, 5‐naphthalenediyl unit, is reversible when an initially oxygen‐free solution of 1 in water also containing 9‐anthracenecarboxylic acid as a photosensitizes and triethanolamine as a “sacrificial” reluctant is irradiated and then aerated. The absorption and emission spectra of the solution provide conclusive evidence. (Figure Presented.)
